Description
The SiT8102 is the next generation of the SiT8002 program-
mable oscillator with lower phase noise, lower jitter, and a
wider frequency range. SiTime oscillators are the smallest,
high-performance programmable oscillator available and are
suitable for use in high speed serial communications,
consumer, portable, industrial, automotive and computation.
This oscillator is packaged in standard low-cost plastic and
chip-scale IC packages.
System reliability is also increased with the SiT8102 by elimi-
nating the quartz crystal and improved immunity to the
environmental effects of vibration, shock, strain, and humidity.

Absolute Maximum Ratings
Attempted operation outside the absolute maximum ratings of the part may cause permanent damage to the part. Actual perfor-
mance of the IC is only guaranteed within the operational specifications, not at absolute maximum ratings.
Notes:
1. The 3.3V device can operate from 2.25V to 3.63V with higher output drive strength, however, the data sheet specifications cannot be guaranteed. Please contact
factory for this option.
2. The output driver strength can be programmed to drive up to 50pF load. Please contact factory for this option.
